Visual analysis, functional testing, and additional analysis were performed on the returned device.The reported leak issue was able to be confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.A query of the complaint handling database for the reported lot was performed and revealed there is no indication of a lot level quality product issue.The investigation determined that the reported leak issue was related to circumstances of the procedure.Based on the analysis of the returned device, the cause of the leak was likely breakaway joint separation which likely caused the x-ring retainer proximal seal damage; however this could not be confirmed.It could be that the customer encountered excess distal pressure/restriction during use, which caused a separation of the breakaway joint, thus causing the observed leak.Other possible causes for the leak could be damage to the catheter sheath, excess bending of the strain relief causing catheter damage, or over pressurization of the syringe during use; however, these conditions could also not be confirmed.Based on the returned state of the device, the leak and observed damage occurred outside the patient and during attempted device prep.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
